| Abstract: | The adsorption ability of chitosan as an adsorbent for Mn 2+ ,Fe 2+ ,Cu 2+ ,Zn 2+ in aqueous solution was studied and the chelating capability of chitosan is shown using parameters such as absorbency,adsorption capacity,and solution pH.The selectivity for adsorbing metalions is Cu +2 >Zn 2+ >Fe +2 >Mn +2 .The research is of great significance for wastewater treatment. |
